--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:ee4f25999f6832a1c5060b9277222c03d852709a commit r13-4460-gee4f25999f6832a1c5060b9277222c03d852709a Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Dec 2 10:29:11 2022 +0100 c++: Deduce range for structured bindings if expression is not type dependent [PR84469] As shown on the decomp56.C testcase, if the range for expression when using structured bindings is not type dependent, we deduce the finish the structured binding types only when not in template (cp_convert_range_for takes care of that), but if in templates, do_range_for_auto_deduction is called instead and it doesn't handle structured bindings. During instantiation they are handled later, but during the parsing keeping the structured bindings type dependent when they shouldn't be changes behavior. The following patch calls cp_finish_decomp even from do_range_for_auto_deduction. The patch regresses the OpenMP g++.dg/gomp/for-21.C test (3 errors are gone), I'll post an incremental patch for it momentarily. 2022-12-02 Jakub Jelinek <ja...@redhat.com> PR c++/84469 * parser.cc (do_range_for_auto_deduction): Add DECOMP_FIRST_NAME and DECOMP_CNT arguments. Call cp_finish_decomp if DECL is a structured binding. (cp_parser_range_for): Adjust do_range_for_auto_deduction caller. (cp_convert_omp_range_for): Likewise. * g++.dg/cpp1z/decomp56.C: New test. * g++.dg/gomp/pr84469.C: New test.
